Well Marty you should get your facts before you post.
The reason for the boost is the blower puts out many more cu.feet of air than all 4 exhaust valves per cyl. can let out and then the exhaust valves close before the piston completely seals off the inlet ports that are all the way around the middle of the cyl. for even more boost. like putting your finger over the end of a garden hose with the water running. Besides I love my 8 JD's and I love Detroit Diesels, that is why I wish JD put them in from the factory not so I could win at the pulls, BUT I WOULD IF JD DID if every thing is up to snuff Balance, tires, air pressure and etc. (but you need to know how to make a Detroit run). These facts are out of Detroit manual.
Proper air box pressure is required for sufficient air for COMBUSTION and SCAVENGING, Lack of power or black or gray smoke are indications of LOW air box pressure.
AIR BOX PRESSURE 1 in. mercury = .49 P.S.I N75 injectors = 31 in mercury that = 15.5 P.S.I
These facts are out of Detroit manual.
Hope this helps you understand how a Detroit Diesel works.

You are forgetting about all the other cylinders-if detroits where a one cylinder then your garden hose theory would be right-all the cylinders are all in the same air box so their cant be any boost made. You are also forgetting about the air box vents-or are these mabee new to you? With low air box pressure your exhaust will not get blown out of the cylinder completly and you will get darker smoke and loss off power-it is not from lack of compressed clean air. Dteroits are a great engine with just a differant way of doing things, I just wish that being a little differant wouldnt be held against them.They should be pulling in the naturally aspirated classes.Not much for arguing but just wanted to voice my opinion-have a good day
